Understanding credit card
interest-free periods
A credit card interest-free period is the time between making a purchase on your card and when interest may begin to apply to that purchase.
Understanding how your credit card billing cycle, statement and payment due date work together can help you make the most of this feature.
What is a credit card interest-free period?
A credit card interest-free period (also called ‘interest-free days’) allows you to make new purchases without paying interest for a period of time, provided you meet the applicable repayment conditions.
What ‘up to 55 days interest free’ typically means
You'll often see American Express Credit Cards offering up to 44 days or up to 55 days interest free1. This refers to the maximum number of interest-free days available on eligible credit cards. The actual number of days depends on when you make your purchase within your statement period (also known as your billing cycle). Purchases made earlier in the billing cycle generally receive more interest-free days than those made closer to the end of your billing cycle.
For example, a typical statement period is 30 days. On a card with up to 55 interest-free days, there would be 25 days after the billing cycle ends to pay the closing balance and avoid being charged interest.
When do interest-free periods apply?
Credit card interest-free periods usually apply to your new purchases, such as everyday spending, online shopping, travel bookings and household bills.
They won't apply if you carry forward a balance from a previous statement, don't pay your full closing balance by the due date or make transactions that are excluded under your card's Terms & Conditions.
Here is a quick summary on how interest-free days work.
Using interest-free periods to manage spending
An interest-free period can help with everyday spending by giving you time between making an eligible purchase and paying for it.

Managing everyday purchases
An interest-free period may help when regular costs, such as groceries, transport, or household bills, fall at different points in the month.
Rather than each purchase needing to be paid immediately, eligible purchases are brought together in your statement, giving you a clearer view of what is due and when.
Check out what you can use your credit card for.

Planning for large purchases and travel bookings
For larger purchases or seasonal spending for travel or holidays, the interest-free period may help by giving you a defined window between making those purchases and needing to pay your closing balance.
This can make it easier to space purchases across a busy period, rather than having every cost leave your account immediately.
The benefit is visibility and timing, not reduced cost. You still need to be confident that you can pay the full amount due.

Interest-free days vs cash flow days
Credit card interest-free periods and cash flow days are both designed to provide flexibility between making purchases and making payments, but they apply to different types of American Express Cards and work in different ways.
Interest-free periods are a feature of credit cards. Eligible Amex Charge Cards such as the American Express® Platinum Card and Amex Business Charge Cards instead offer cash flow days4.
What are cash flow days on charge cards?
- Cash flow days refer to the period between making an eligible purchase on an Amex Charge Card and your payment due date. Unlike a credit card, a charge card does not have an interest-free period because the balance is generally due in full each statement cycle. Learn more about charge cards.
- As for interest-free periods, the number of cash flow days you receive depends on your card, when you make a purchase within your billing cycle. Purchases made earlier in your statement period will have more cash flow days before payment is due than purchases made closer to the end of your billing cycle.

Frequently Asked Questions
Your credit card billing cycle, also known as your statement period, is the period during which your credit card transactions are recorded before your monthly statement is issued.
An interest-free period is the time between making an eligible purchase and when interest may begin to apply. The length of your interest-free period depends on where your purchase falls within your billing cycle and whether you meet the applicable repayment conditions.
Yes. If you don't pay your full closing balance by the payment due date, or if you've carried forward a balance from the previous statement period, interest may apply to eligible purchases in accordance with your card's Terms and Conditions.
Not necessarily. Paying only the minimum payment helps keep your account in good standing, but it may not preserve your interest-free period. To avoid interest on eligible purchases, you'll generally need to pay your full closing balance by the payment due date and meet the applicable repayment conditions.
No. Interest-free periods are a feature on Amex Credit Cards1. Amex Charge Cards don't offer interest-free periods. Instead, they may offer cash flow days4, which provide time between making eligible purchases and paying the statement balance by the due date.
No. While both features provide time between making a purchase and making a payment, they work differently. Interest-free periods apply to credit cards and are subject to repayment conditions. Cash flow days are available on charge cards, where the card balance is generally due in full each statement cycle.
